RNA Virus
This non-enveloped virus is small and causes the “common cold.”
Rhinovirus
This enveloped virus is the largest virus and causes smallpox and cowpox (but NOT chickenpox!).
Poxvirus
This is a complete virus unit made of nucleic acid, a capsid, and possibly an envelope.
Virion
The stage where viruses leave the host cell.
Release
Name at least one reason why viruses are considered “living”
1. Contain either DNA or RNA genetic material
2. Can reproduce with the assistance of host cell
EXTRA: Can undergo mutation
This enveloped virus is medium sized and causes Rabies.
Rhabovirus
This non-enveloped virus is small and causes warts.
Papovavirus
These attack plants; not humans, and caused potato spindle tuber disease.
Viroid
: The stage where viral DNA is injected into the host cell; uses lysozymes, or fusion to weaken the cell wall.
Penetration
Name atleast 1 reason why viruses are considered “Non-living”
1. Cannot reproduce by themselves
2. No metabolism (cannot create apt)
3. They’re not made up of cells
This enveloped virus is medium-sized and causes Influenza (Spanish flu).
Orthomyxovirus
This enveloped virus is large, known for latency, and causes herpes, chickenpox, and cold sores.
Herpesvirus
These rare infectious particles have no nucleic acid and are made purely of protein.
Prion
The stage where the assembly of new parts to create a complete virus.
Maturation
Name all five steps of viral replication in correct order
1. Attachment
2. Penetration
3. Biosynthesis
4. Maturation
5. Release
This non-enveloped virus is medium-sized with a double capsid and causes Rotavirus.
Reovirus
This virus affects the liver and causes hepatitis.
Hepadnavirus
An infectious particle too small to be a virus that has one specific DNA and no capsid.
Viroid
The stage where attach to the cell membrane at receptor sites on the host cell.
Attachment
Explain the difference between teratogenesis and teratogen.
Teratogenesis refers to the defect caused during the development of a fetus while the teratogen refers to the specific agent that caused the defect.
This enveloped virus is medium-sized, likes mucous, and causes measles and mumps.
Paramyxovirus
This non-enveloped virus is medium-sized, highly resistant to chemical chemicals, and cause respiratory infections.
Adenovirus
These cause spongiform encephalopathies like mad cow disease and sheep scrapie.
Prions
During this stage, the virus inserts its DNA into the host, genetic material to produce new viral nucleic acids and proteins.
Biosynthesis
Name all of the oncogenic (cancerous) virus families (DNA/RNA)
Hint: RNA only has one!
DNA - Adenoviridae,Herpesviridae,Poxviridae,Papovaviridae,Hepadnaviridae
RNA - Retroviridae
